Brake line question

Hi, I am about to replace the rear brake lines on my daughter's '00 Grand Prix. I was under there figuring out how much line I am going to need, and spraying fittings with PB blaster.
Does anyone know off the top if their head what thread size, and what type of flare the lines are where they connect to that fitting near the end of the line? I was going to disconnect it, but figured I should let the PB Blaster soak in first. I think it's a metric/bubble flare, but not sure.
Thanks.
 


Good trick to getting the fitting off is to cut the line right behind it and then use a socket on it. I am pretty sure the grand prix still use the metric flare. I would leave the old line in and just run the new one right next to it to avoid braking any more lines.
